@Sage Weil : in which kernel version can I found this fix please ?
Updated by Sage Weil over 10 years ago
- Status changed from Resolved to Pending Backport
the fixes just went upstream to linus's tree and are not in a released kernel yet. as soon as they appear there i will send them to stable@ for the next stable kernel updates.

Hi,
I had this bug just now (see below), with a 3.10.16 kernel, with patches from your Git (cf attached file), and Ceph 0.67.4.
I did something wrong ?

Hi Olivier,
Can you attach the entire dmesg or at least a few minutes worth of
messages prior to the assertion failure splat in each case? Also, can
you describe your workload and what exactly was happening at that time?
Updated by Olivier Bonvalet about 10 years ago
Hi,
well, there is nothing else in dmesg, except several hours before this hang.
This servers are running about 30 VM (Xen paravirtualisation), using 5 RBD images each one (so about 150 RBD images are mapped on each server). For me there is nothing "special" at this hours : snapshot are created and removed only at night, and I have hang at all hours.
Those VM are essentially small LAMP servers.
If it can help cluster stats are : pgmap v39011655: 5168 pgs: 5168 active+clean; 14347 GB data, 51970 GB used, 28264 GB / 80235 GB avail; 4013KB/s rd, 67873KB/s wr, 2679op/s
Note that servers "murmillia" and "rurkh" are also MON servers.

I haven't got this problem anymore, it seems really stable for me now. Thanks !
I think the issue can be mark as resolved.
Updated by Ilya Dryomov about 10 years ago
Just in case, the fix you are running with is now in 3.14. However we
are still working on a better fix, so we'll keep this open for a while.
Updated by Ilya Dryomov almost 10 years ago
- Status changed from In Progress to Resolved
Should be fixed by commit 0f2d5be792b0 ("rbd: use reference counts for image requests"), which went into 3.16-rc1.

How did you overcome this Bug? Applying the patch in 3.13.5 or upgrading to a newer kernel?

Which version of 3.14 is this fix applied to please? - I was not able to see anything in the change logs.

Sorry, please ignore this I can see the patch applied in 3.14.8 at least.
